Corpse flower spectacular

The last few days have been exciting for plant lovers in our college town. On Thursday, a titan arum (Amorphophallus titanum) at UC Davis’ Botanical Conservatory started to bloom. This is only the 5th time a titan arum has bloomed at UC Davis, and I finally got a chance to see this extraordinary event in person. We arrived at 2pm, a few hours after the peak (around 9am this morning), but it was still an impressive sight. According to the docent at the Conservatory, they expect the flower to close by this evening, and that’s the end of it. Just four short days!

The titan arum, native to the steaming jungles of Sumatra, is considered to have the largest inflorescence of any plant in the world. The one I saw today was relatively small (maybe 4 ft. from soil level to the top of the spadix), but blooms inflorescences as tall as 9 ft. have been recorded.

The “flower” itself would be spectacular enough, but the main attraction is the smell. There is a good reason why the titan arum is nicknamed corpse flower or carrion flower. The smell is usually described as rotting meat, and it smelled exactly like that, with a fishy component to it. Very intense, sharp, nasty, and yet intriguing, considering it comes from a healthy plant, not a pile of rotting organic matter. The odor attracts flies and carrion beetles who in the process of crawling all over the spadix get covered in pollen which they then might carry to other titan arums in bloom nearby. Visit the web site of the UC Davis Botanical Conservatory for a good explanation of the process.

According to Wikipedia, only about 100 titan arum blooms have been recorded in cultivation. Check out this detailed list.

If you ever get a chance to see of these plants in bloom, don’t miss it. It truly is something special. And if you’re interested in having something similar in your own yard, try a much smaller relative called Amorphophallus konjac. Four years ago I was given a handful of quarter-sized corms by a botanical student at UC Davis, and I planted them in our backyard against the street-side fence. Every year they’ve put up a stalk and leaf, and I’m hoping that in another couple of years they might bloom.

  1. Was Reba's VooDoo Lily a relative of this? Beautiful, but surprised that you could keep a pleasant expression on your face!

  2. Dick: Rank has its priviledge!

  3. You could probably take some of those seeds and grow your own. I thought about getting them, but they would probably struggle through the winters here.

  4. Steve, from what I read, growing A. titanum is anything but trivial. It needs perfect growing conditions, including high humidity. I'm almost sure it wouldn't grow outside here; too dry in the summer and too cold in the winter. Apparently the corms are highly vulnerable to nematodes. There's got to be a reason why there are so few of them around :-).

  5. Good timing Gerhard!! I've never had the chance to see one just on the right time, always a few days before or after when the flower has already collapsed.

    And you're a brave man getting that up close to the flower!

  6. Wow again Gerhard your photos are outstanding. How cool that you were there seeing it bloom. I wish computers had a smellovision or something. And I went to the web site and watched the fruit develop. Very interesting and cool looking.

  7. Wow, to be able to take a photo of the corpse flower at this stage of bloom. Definitely a once in a blue moon moment.

  8. I have the Amorphophallud konjac in my front yard. It never bloomed. Is it going to happen someday? do I need to do something special? I was able to plant a stinky flower in a pot once. Now I`m looking to get it from anywhere because it was beautifull and didn`t stink almost at all and it was not so big. I got it from the bahamas. Maha

    1. I have three Amorphophallus konjac and they haven't bloomed either. It's simply a matter of time. The tuber has to be a certain size before it produces a flower. From what I recall reading, the plant has to be about 10 years old.
